My research focuses on synthesis and characterization of semiconducting quantum structures for use in energy efficient light emitters and solar cells. Since 2006 a strong focus is being made on heterostructured III-V semiconductor nanowires grown by molecular beam epitaxy. Fabrication of nanowire devices is being explored by electron beam lithography, nanoimprint and focused ion beam techniques. Opto-electronic characterization of e.g. nanowire quantum dots using techniques such as low temperature photocurrent and electroluminescence is done in order to understand and utilize quantum size effects for future photonic and photovoltaic device applications.
